Need help installing another OS in dual boot with windows8

Hey all...

As i have stated in my topic, i need to install opensuse in dual boot with windows8. I have just purchased samsung NP550P5C-S03IN, series 5 laptop with core i7, it came with windows 8. Ok so now i'm having both usb boot device and even the bootable dvd of opensuse 12.2, but even after putting both things into the laptop, the laptop boots directly to windows 8, it doesnt show any "to boot from" option. I tried fixing it by going into bios and setting up boot device priority, but when i looked under the boot tab there was only one option stating to "boot from windows boot manager", there was no option to boot from removable device. So now i'm stuck with this problem, if any one is having any idea on how to resolve this, then please reply.

Thanks in advance.

Have you look at install in a VM.
